How much is it to send a short message to Radio Beijing?

There are many channels in Radio Beijing, and the charges for each frequency are different, ranging from 1 yuan in 0.2 yuan and 0.5 yuan, excluding communication fees. Different programs on the same channel may also be different.

I sent 0.2 to the Voice of the Economy and the Urban Service Management Broadcasting, and I don't know anything about Beijing literature and art, traffic broadcasting, literature and art broadcasting and sports. Personally, I think 0.2 and 0.5 are more common.
